  1. 1. HEMPEL Dear paint user, This updated edition of Hempel's Coating Reference Handbook has been put together to help you get the best possible performance from Hempel's paints. Originally developed as a tool for our own Coating Advisers by Hempel's Centre for Applied Coatings Technology, we hope a wider audience can benefit from the practical advice, data, references, procedures, equipment and standards used within the coatings industry. Our own Coating Advisers use Hempel's Coating Reference Handbook every day and we hope that you will also be able to put it to frequent good use in getting the best out of your daily work with paint and coatings. Pierre-Yves Jullien CEO, Hempel

  7. 7. HEMPEL SUBSTRATES S1 During your job you may run into a number of different substrates that has to be coated. Below is given a list of the most common ones, and where you may meet them. ORDINARY STEEL TYPES Constructional steel Consider all these types equal. Same surface preparation acc Cast Iron to ISO 8501-1:1988. Cast Iron may have porous surface Cor-Ten Steel Therefore zinc silicates are not recommended on cast iron STAINLESS STEEL TYPES Muffler Grade Steel Muffler Grade is low quality Stainless Steel which should allways Stainless Steel be painted: The others are the same Seawater Resistant paintingwise. Stainless Steel For instruction see S2 ALUMINUM Extruded sheets All types to be treated equal. and profiles. Cast aluminium should always be abrasive blasted Cast For instruction see S3 METAL COATED STEEL Hot dipped Galvanised Steel, fresh. All unexposed surface should be treated equal. Hot dipped Galvanised Steel, weathered Weathered surfaces are usually easier to paint. Electrolytic Galvanized Steel Sheet Zinc - Aluminium Galvanized Steel For instruction see S4 METALLIZING Zinc Sprayed Metallising All surfaces to be treated equal Aluminium Sprayed Metallising Zinc - Aluminium Metallizing For instruction see S5 CONCRETE All types Surfaces preparation and sealing depend on later exposure. For instruction see S6 When meeting other substrates or in doubt always consult your TSD-Manager INSPS1 ed2 VALIDITY SUBJECT TO CONFIRMATION 13/05/98 EMi
  8. 8. HEMPEL STAINLESS STEEL TYPES S2 Most commonly used Stainless Steel types are: TYPE: ALLOYING COMMON USE: Muffler Grade Steel8 -12 % Chromium Side ond roof panels on Containers. Stainless Steel: 18-21% Chromium Chemical tanks and equipment. + 8-11% Nickel Side ond roof panels on Reefer Containers. Panels on transportation equipment Seawater ResistantAs Stainless Steel + Various minor equipment in Stainless Steel: 2-3% Molybdenium contact with sea-water (Filters etc). SURFACE PREPARATION: Surface preparation allways depends on later performance exposure. The more severe - the more thorough surface preparation is required. For these substrates you cannot talk about ISO 8501-1:1988 and similar, since no millscale or rust is present on the surface. What matters is to obtain the necessary adhesion of the coating. Later Performance Exposure: Min surface prep Primer type Total DFT MILD Degreasing 1, 2, 3 or 4. 80-110 micron MEDIUM Degreasing 1, 2, 3 or 4. 110-150 micron (+ Phosphating or Abrasive Sweeping) SEVERE Abrasive Sweeping Standard Epoxy 150-300 micron to a dense profile Barrier Coating IMMERSION Abrasive Sweeping Standard Epoxy 250-300 micron to a dense profile Barrier Coating Primer Type (2006-status): 1: For Alkyds HEMPEL'S UNI PRIMER 13140 2: For Physically Drying HEMPADUR 15552 3: For Epoxies and PU.s HEMPADUR 15552 4: For WB Acrylics HEMUCRYL 18200 or HEMUCRYL 18032 Indicated HEMPEL primers may not necessarily be found in the HEMPEL Book.

  9. 9. HEMPEL ALUMINIUM S3 Most commonly used Aluminium types are: TYPE: COMMON USE: Extruded sheets and Structural Elements, Facade Panels Profiles: Side ond roof panels on Reefer Aluminium Hulls, Superstructures. Containers and on transportation equipment Anodized Aluminium: Sheets and profiles treated chemically to increase oxide layer. Cast Aluminium: Various minor equipment SURFACE PREPARATION: Surface preparation allways depends on later performance exposure. The more severe - the more thorough surface preparation is required. What matters is to obtain the necessary adhesion of the coating. Anodized aluminium cannot be painted directly. The anodizing must be removed beforehand by mechanical methods (abrasive blasting). Later Performance Exposure: Min surface prep Primer type Total DFT MILD Degreasing 1, 2, 3 or 4. 80-110 micron MEDIUM Degreasing 1, 2, 3 or 4. 110-150 micron (+ Phosphating. or Abrasive Sweeping) SEVERE Abrasive Sweeping Standard Epoxy- 150-300 micron to a dense profile barrier system IMMERSION Abrasive Sweeping Standard Epoxy- 250-300 micron to a dense profile barrier system Primer Type (2006-status): 1: For Alkyds HEMPEL'S UNI PRIMER 13140 2: For Physically Drying HEMPADUR 15552 3: For Epoxies and PU.s HEMPADUR 15552 4: For WB Acrylics HEMUCRYL 18200 or HEMUCRYL 18032 Indicated HEMPEL primers may not necessarily be found in the HEMPEL Book. Avoid copper containing anti-foulings on immersed areas of aluminium hulls. INSPS3 ed6 VALIDITY SUBJECT TO CONFIRMATION 17/05/05 EMi
  10. 10. HEMPEL GALVANIZING S4 Most commonly painted Galvanizing (Metal Coating) types are: TYPE: COMMON USE: Hot dipped Galvanizing: Structural Elements, Lightpoles, Handrails, (Fresh) Roadguards. Side and roof panels on Reefer Containers. Hot dipped Galvanizing: As fresh hot-dipped galvanizing. (Weathered) Electrolytic galvanizing: Sheets, bolts and minor equipment. Zinc-Aluminium Galvanizing (Sendzimir) Sheets, Facade Panels SURFACE PREPARATION: Surface preparation allways depends on later performance exposure. The more severe - the more thorough surface preparation is required. What matters is to obtain the necessary adhesion of the coating. Any white rust protection treatment of electrolytic or Sendzimir galvanizing must be removed. Later Performance Exposure: Min surface prep Primer type Total DFT MILD Degreasing */ 1, 2, 3 or 4. 80-110 micron MEDIUM Degreasing+ 2, 3 or 4
